Apple released Bootcamp 2.1 with OS 10.5, which allows you to dual boot to Windows XP/Vista on your Mac.
Subsequenet to that release, there was a driver update for the Multitouch trackpad which was suppose to improve souble tapping, etc. However it caused a Blue Screen of Death (BSOD) the moment you double tapped, courtesy of applemtp.sys.

Many people sent suggestions to Apple to fix this, but it seemed to be falling on deaf ears.

Little did we know that Apple were releasing a new version of the touchpad driver included with Bootcamp 3.0 on the Snow Leopard install DVD.

I’ve updated my Bootcamp to 3.0, and indeed the applemtp.sys driver version has increased to 2.1.2.112. The FAQ for the Snow Leopard update states that Bootcamp 3.0 has:

“Improved tap-to-click support – The ability to tap the track pad to click the mouse button is now supported on all Mac portables that run Boot Camp.”

In my tests, so far, there has been no more crashes. I get to use double finger right click tap, and the track pad responsiveness that I got in the older buggy driver is back as well.

Thanks Apple. No more BSOD.
